Complete Dynatrac ProRock 60 High-Pinion Semi-Float Rear Axle Assembly for Jeep Wrangler JK
The Dynatrac ProRock 60 High-Pinion Semi-Float Rear Axle Assembly is built for Jeep JK owners who demand maximum strength, durability, and ground clearance without the weight and complexity of a full-float axle. Designed as a complete, bolt-in rear axle solution, this ProRock 60 is ideal for aggressive off-road use, large tires, and high-torque applications where factory axles fall short.
At the core is Dynatrac’s patented ProRock nodular-iron center section, engineered to provide superior gear support, increased rigidity, and unmatched ground clearance compared to conventional Dana-style housings. The high-pinion configuration improves driveshaft angles and strength, making it an excellent choice for lifted JKs running larger tires.
This axle assembly is fully assembled and ready to install, delivering proven ProRock 60 performance in a semi-float design that balances strength and weight for trail and street use alike.
